GENERAL
INTRODUCTION
The MC68HC05C5 is a 40-pin device based on the MC68HC05P7. The memory map
includes 5184 bytes of user ROM, 176 bytes of RAM, and 128 bytes of EEPROM. The
MCU has four 8-bit I/O ports: A, B, C and D. Port C has high sink current capability. The
MC68HC05C5 includes a simple Serial I/O Peripheral (SIOP), 16-bit Timer, and an on-
chip Computer Operating Properly (COP) watchdog circuit.
